Research done in the US and UK has found that physical attractiveness is often judged by factors such as skin clarity and vivid color in the eyes and hair. This most likely stems from the human instinct of survival: A person’s facial features are an indication of health and the ability to create life. If the uniqueness of our eye color can influence our appearance, what other aspects of our existence can eye color affect?
The highest optical perspicacity ever measured was achieved by an Aboriginal man. As a whole the Australian Aborigine population, who are a brown-eyed bunch, possess visual acuity superior to that of European descendants who have light colored eyes. Specialists have reported that this group suffers less high myopia and astigmatism than Europeans. Historical diaries written by colonists attest to the amazing eyesight the Aborigines possess. One story spoke of an Aborigine man who could spot a whale on the horizon that the European colonist could not see at all. Why would the Aborigine people have such superior vision? Most experts suspect it is partly genetic, partly eye exercise and mostly that they spent almost all of their time outdoors.
The Greatest Ability to See Color
While individuals with dark eye colors are thought to see more accurately, people with light eye colors see more vivid colors. The highest ability to see color ever confirmed was a light-blue eyed woman from England who underwent the Farnsworth-Munsell 100-Hue and Rayleigh Match tests. These examinations proved her peripheral vision allowed her to distinguish color and shape more clearly.
Scientists explain that the density of receptor cells on the eye retina is greatest at the center and lowest at the edges. Light-eyed individuals may have better peripheral vision and have the ability to fare better in self-paced assignments, like playing golf, pitching a ball or bowling. In contrast, a separate scientific study authored by the University of Louisville found that dark-eyed people have better reaction times than light-eyed individuals, and therefore fare better in sports like boxing, baseball or playing defense in a football game.
The Worst Eyesight Recorded
Research suggests that Japanese people tend to have the worst eyesight of any national group. An estimated 90% of individuals post-school age have diminished vision, and 1 out of 20 men are color blind. Why? There are two popular beliefs. The first is that it is simply genetic; the second school of thought is that Asian parents make children read for too long periods of time, and that has an effect on the child’s ability to see.
The concept of too much reading may be a popularly held belief, but scientists disagree. Instead, some research points to an explanation that vision problems in Japan may be caused by decreased exposure to sunlight. Scientists point out that once they reach school age, Japanese students spend little to no time outdoors. Direct sunlight has been proven to increase the release of dopamine, which prevents the eyeball from growing into a distorted shape found in those with myopia. Like the example of the Aborigine population, having superior eyesight might be linked to increased time spent outdoors.
Does eye color affect vision? Although some studies have provided us with fascinating arguments, there really is no conclusive evidence to support this theory at this time. More scientific studies are needed to investigate this idea further. Regardless of the outcome though, there are plenty sight-enhancing options to level the “playing field,” including contact lenses.
